A “bond beam” refers to a reinforced element that is placed horizontally in a masonry wall to withstand shear loads as well as disperse lateral loads all through the wall section. The bond beam transmits horizontal strength to a wall where it is not possible to be fortified with floor or roof structure. Bond beams enclose steel reinforcing in grout or concrete, ties the structure all together horizontally, and frequently interlock with supplementary vertical reinforcement. A bond beam is generally built adjacent to the top of a freestanding wall. A bond can also be applied to deliver a stable anchorage toward floor or roof structure. Bond beam assemblies are generally found in construction made with concrete masonry units, where special shapes allow the beam to be merged with the wall construction, but may also be constructed with brick or developed in concrete.
A single bond beam contains two courses of AB Fence Panel Block and their cores are filled through sand mix grout. Horizontal steel is arranged amid the two courses of block and reinforce the whole bond beam. To provide extra support, wire stirrups are arranged in each of the first two cores from each end and almost each other core with at least one stirrup per block, to make sure that the courses are not detached. This bond beam configuration develops a robust structural beam that can easily reinforce the fence panel structure. Bond beams are mostly applied at the top and bottom of the fence panel to produce a coordinated fence panel structure. Intermediate bond beams are necessary when the height of the AB Fence is raised.
Bond beams are occasionally haphazardly arranged in walls as a stiffening or tie element at tops of walls, floor connections, and top of foundation walls. Intermediate bond beams are generally not essential if not required to withstand shear stresses or to satisfy minimum seismic reinforcement requirements.
